Usain Bolt regained his world 100 metres crown and restored some
credibility to a sport tarnished by a plethora of doping scandals as he
scorched to gold in 9.77 seconds at Moscow's Luzhniki Stadium on August
Fast-starting American Justin Gatlin took silver in 9.85 with Jamaican Nesta Carter securing bronze in 9.95.
from the 2011 final for false-starting, Bolt made no mistake out of the
blocks this time and although trailing Gatlin, directly to his left, at
halfway, he surged to the front at 60 metres.
